Question:

8. A sample of difference scores from a repeatedmeasures experiment has a mean of MD 5 with a variance of s 2 64.

a. If n 4, is this sample sufficient to reject the null hypothesis using a two-tailed test with .05?

b. Would you reject H0 if n 16? Again, assume a two-tailed test with .05.

c. Explain how the size of the sample influences the likelihood of finding a significant mean difference.
